This project contains Terraform scripts to provision Google Cloud infrastructure resources required to deploy SAS Viya 4 platform products. Here is a list of resources this project can create -

  • VPC Network and Network Firewalls
  • Managed Google Kubernetes Engine (GKE) cluster
  • System and User GKE Node pools with required Labels and Taints
  • Infrastructure to deploy SAS Viya platform CAS in SMP or MPP mode
  • Shared Storage options for SAS Viya platform - Google Filestore (ha) or NFS Server (standard)
  • Google Cloud SQL for PostgreSQL instance, optional

Architecture Diagram

Once the cloud resources are provisioned, see the viya4-deployment repository to deploy SAS Viya 4 platform products. If you need more information on the SAS Viya 4 platform products refer to the official SAS® Viya® platform Operations documentation for more details.

Authenticating Terraform to access Google Cloud

See Terraform Google Cloud Authentication for details.

Customize Input Values

Create a file named terraform.tfvars to customize any input variable value documented in the CONFIG-VARS.md file. For starters, you can copy one of the provided example variable definition files in ./examples folder. For more details on the variables declared refer to the CONFIG-VARS.md file.

NOTE: You will need to update the cidr_blocks in the variables.tf file to allow traffic from your current network. Without these rules, access to the cluster will only be allowed via the Google Cloud Console.

When using a variable definition file other than terraform.tfvars, see Advanced Terraform Usage for additional command options.
